They fit pretty good and even better if I wanted to mount them closer like another member is doing. I just stuck them in the exsisting holes with some washers to check them out. They can be lowered a bit but would need to drill new holes. The bottom has a little bit of a gap but easily filled with black silicone, weatherstipping, rubber, what every suites your fancy. I have another set for the rear but have not removed the bumper yet.
The right side is off due to some body damage there I need to address. I may end up using them as untill I can figure out my split front and rear bumper mock up. For $60.00 its WAY cheaper then the alternative!
Oh whats that? what are they off of???? Do I dare tell, I know that someone already knows as its where I got the idea to try them out. So post up your guesses...
They are off a 1973-1974 Porsche 914 rear bumper guards #914-605-063-10 for the left and the right Ill have to check but from VW parts experience its probably 914-605-064-10. I have a set of the fronts but dont fit as nice as the rears. They may work better for the rear but I have 3/4 tank of gas and did not want to finish taking out the tank yet. 
. Appropriate for the cooler climates.
